AbstractThis research work describes a non-invasive and label-free immunosensing technique to detect the C-telopeptide of type-I collagen (CTX-1) by Electrochemical Impedance Spectroscopy (EIS). A planar interdigital capacitive sensor is used to evaluate the properties of the material under test. This sensor was fabricated on the basis of thin film micro-electromechanical system (MEMS) semiconductor device fabrication technology. EIS was used in conjunction with the sensor to detect collagen type-I in blood plasma. At the first stage, the Serum CrossLaps® ELISA was used to measure some known samples in order to obtain a standard curve. Streptavidin agarose was successfully immobilized on the sensing area of the sensor. After that the experiments were done with antibody solution and three known samples of CTX-1, zero concentration which was considered as control, 2.669 ng/ml and 0.798 ng/ml concentration. The results are encouraging for further investigation.
